Why is image cropping so hard?

I've been using the CI image lib. No worries resizing, it's just fine.

But cropping? I just can't make it work.

Code:

$config['x_axis'] = 100;
$config['y_axis'] = 100;
$config['width'] = 100;
$config['height'] = 100;

Now, that code should reference a block 100 x 100, starting 100 in from the left (x) and 100 down from the top (y).

Right?

But no, I get an image that varies depending on the source image. One dimension is correct, but the other appears to vary depending on the source.

I'd kill for a simple example of a crop operation.

Try just not bothering with the CI image lib...

PHP GD's imagecopyresized/imagecopyresampled is very easy to implement.

Sure, but it's kinda weird that it doesn't perform as expected.

set aspect_ratio setting to false

Well, works perfectly now!

The $config['maintain_ratio'] defaults to true, so it must be set.

Thanks!

I've always dreamed of building a CI library to use this: http://odyniec.net/projects/imgareaselect/. It's the only real solution for handling dummy users.

Yeah, I used the great little Jcrop script for that. Great addition for users.
